Prevent empty and invalid section names

[chelsea-tnc]

What this change does:

• Prevents users from entering blank or only whitespace characters for section titles
• Prevents users from using "archive" for section titles, since it's reserved
• Adds more unit tests

How to test:

• Go to the Sections admin in TinyCMS. Click "Add Section."
• Enter nothing, click Submit. You should see an error and the section should not get saved.
• Enter spaces, click Submit. You should see an error and the section should not get saved.
• Enter "archive," click Submit. You should see an error and the section should not get saved.
• Enter "archives," click Submit. The section should get saved successfully.

In the future, we can add some more logic to prevent duplicates, etc. This particular fix is scoped to error handling only and preventing deployment issues due to bad data.

Tested locally but may need to check-in to main to test closer to the results in production. But, here are my results.

Results:

1. Section with blank and space:

2. Section with 'archive'

   

3. Section with 'archives'

   

4. Added a number and characters and it was able to be added. We could eventually add exceptions for this too
